One of his lawyers, Tranquil Salvador III, told media that Corona is now under sedation.

Corona was brought to Medical City after he left the Senate impeachment court on Tuesday night, defense spokesperson Atty. Karen Jimeno earlier said.

DZMM's Robert Mano reported that Corona arrived at Medical City around 8 p.m.

He allegedly entered discreetly through the basement and not the main entrance.

Corona was reportedly accompanied by his wife and 2 men in white.

The chief justice allegedly suffered from hypoglycemia while he was on the witness stand in his trial on Tuesday, which triggered his apparent walkout from the Senate session hall after he gave a statement.

Jimeno: No walk out

Jimeno, meanwhile, claimed that Corona did not intend to walk out of the Senate session hall.

"It's unfair to conclude he walked out. He wasn't feeling well. He declared near the end he wanted to be excused," she said.

Jimeno also said the defense team did not know the contents of Corona's opening statement beforehand.

After his apparent walkout, Corona returned to the session hall on a wheelchair.

However, his chief defense counsel Serafin Cuevas said his client was not fit to continue taking part in the day's hearings.

Cuevas apologized for Corona's apparent walkout and asked for understanding from the court.

Enrile, however, remained unconvinced and gave Corona until Wednesday to allow himself to be cross examined or his statement given in court on Tuesday will be stricken off the record.

"Pinayagan ko siyang magsalita nang mahaba. Wag niyo naman kaming babastusin," Enrile said. "I will not allow any abuse of authority against this court for as long as I am presiding officer."
